Nettet31. okt. 2024 · Therefore, one single rack-type hob can be used to produce gears with any number of teeth and then paired with each other. Thus, a 6-tooth gear (red) is produced with the same tool as an 18-tooth gear (green) or a 9-tooth gear. This applies not only to gear hobbing, but also to gear shaping and gear planning. edward elmhurst webmail

Influence of fillet radius of hob top edge on tooth surface …

NettetA flat-root ramp on the hob tooth profile will generate a chamfer on the tooth to provide clearance at the major diameter between the external and internal mating teeth. A fillet-root spline hob has a smooth radius so as not to generate a hard chamfer on the spline teeth tips. Download the brochure.
